A particle moves on the number line
shown in figure A.Figure A The position of
as a function of time is shown in
figure B. (Note: The graph of
shown in figure B is not
the path of the particle; it is a plot of
the particle's position versus time.)
(a) When is moving right? help (intervals or inequalities)
(b) When is standing still? help (intervals or inequalities)
(c) When is the velocity of negative? help (intervals or inequalities)
(d) On a sheet of paper, graph the particle's velocity and speed
(where defined).
